Steam is downloaded and installed correctly because the online installer will need network connection to fulfill it's setup.
Please check whether the internet connection is working because it needs for signing in your steam account.
If there is something wrong with your account e.g. account blocked, forgot password or anything similar than contact steam help and support
If you have old steam software installed than uninstall it and download it from 3rd party e.g. https://filesmint.com/steam/ and install it after a system restart.
After it you will find all of your games will be listed under my games
You can also sign in to steam account on their website without downloading steam software.
